Description

Technical Field

[0001] This utility model belongs to the technical field of transfer devices, specifically relating to a transfer device for the production of aerated concrete blocks. Background Technology

[0002] Aerated concrete blocks are a lightweight, porous, and environmentally friendly new type of building material. Due to their excellent thermal insulation properties and low density, they are widely used in the construction industry. In the production process of aerated concrete blocks, the finished blocks need to undergo cutting, steam curing, and other processes, and finally need to be transferred to storage areas or transport vehicles for loading. However, because aerated concrete blocks are relatively fragile and prone to slippage and damage during transportation, how to efficiently and safely complete the transportation and loading operations of aerated concrete blocks is an important technical issue of concern in related fields.

[0003] Currently, the transportation of aerated concrete blocks often relies on manual handling or simple brackets for loading and securing. This method is not only labor-intensive and inefficient, but also prone to causing blocks to tilt or fall during transport due to the poor adaptability of the securing devices, affecting the stability of the transport. Furthermore, some existing transport devices use fixed enclosure structures that cannot be folded flexibly when not in use, occupying significant storage space and hindering equipment storage and reuse. Therefore, there is still room for optimization in the structural design of existing aerated concrete block transport devices. There is an urgent need for a transport device that can achieve stable positioning, rapid folding, and unfolding to improve the convenience and safety of the transport process. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a transfer device for the production of aerated concrete blocks. Through a reasonable structural design, it can achieve the synchronous folding and unfolding of the first and second support rods, quickly retract the fence during loading, and provide reliable limiting support during transfer, thereby improving the convenience and safety of loading and transfer.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A transfer device for the production of aerated concrete blocks includes a movable frame, a vertical support plate fixed to the upper surface of the movable frame near the left end, and a handle fixed to the left side of the support plate.

[0007] Multiple first support rods that can rotate to the right are installed on both the front and rear sides of the mobile frame, and a second support rod that can rotate to the right is installed on the right end of the mobile frame. The upper ends of the multiple first support rods located on the front or rear side are connected and rotated synchronously through connecting rods. The upper ends of the two first support rods and the second support rod located on the far right are fixedly connected by a stop bar.

[0008] Locking mechanisms are installed on the left side of the support plate near both the front and rear sides. The locking mechanisms lock and fix the leftmost first support rod when it is vertical.

[0009] Furthermore, the mobile frame includes a square frame welded from square tubes, with multiple support bars fixed to the inner side of the square frame, a thin plate placed on the upper side of the square frame, and evenly distributed casters fixed to the lower side of the square frame.

[0010] Furthermore, guide holes are provided at both the front and rear ends of the support plate, and clearance openings are provided on the left side of the support plate at positions corresponding to the guide holes.

[0011] Furthermore, the locking mechanism includes a pin inserted into a guide hole and a push block installed in a clearance opening. A insertion hole for cooperating with the pin is provided on the leftmost first support rod. A spring is provided inside the guide hole to elastically push the pin outward. The push block is fixedly connected to the pin by a fixing screw, and the push block can fix the position of the pin.

[0012] Furthermore, one end of the pin has a groove for receiving the end of the spring, and the side of the pin has a threaded hole for engaging with the fixing screw.

[0013] Furthermore, a locking plate is fixed to the upper side of the push block, and a countersunk hole for installing fixing screws is opened in the middle part of the push block. A locking screw is threaded on the locking plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model provides a transfer device for the production of aerated concrete blocks. Through reasonable structural design, it can effectively solve the problems of poor fixation, cumbersome operation, and large space occupation of existing transfer devices in the process of transferring aerated concrete blocks, thereby improving the convenience, safety and stability of the device.

[0016] This invention employs a first support rod, a second support rod, a connecting rod, and a stop rod to form a foldable fence structure, effectively limiting the movement of aerated concrete blocks during transport and preventing them from falling or being damaged due to shaking or tilting. In existing technologies, transport devices typically use fixed fences, which cannot be folded or unfolded according to loading requirements, leading to inconvenience. This invention, by tightening the locking screws, causes the push block to disengage the pin from the first support rod, thereby achieving synchronous folding of the support rod, making the loading process faster. During transport, a spring-loaded return pin keeps the support rod vertical, and the stop rod further obstructs the aerated concrete blocks, ensuring their stability during transport and improving safety.

[0017] This utility model's mobile frame is welded from high-strength square tubing and incorporates multiple support bars within the frame to enhance overall load-bearing capacity. This allows the device to withstand the weight of aerated concrete blocks, preventing deformation and improving long-term stability. Existing mobile frames have a simple structure and limited load-bearing capacity, making them unsuitable for transporting large quantities of aerated concrete blocks. This utility model, through the rational distribution of support bars and the installation of high-strength nylon casters at the bottom of the mobile frame, enables the device to maintain stable movement even under heavy loads, improving operational flexibility and reducing the burden of manual handling.

[0018] This invention's locking mechanism employs a combination of a pin, push block, and locking screw, ensuring stable fixation of the support rod in a vertical position. A spring enables automatic reset, preventing loosening due to vibration and improving fence safety. In existing technologies, some locking mechanisms use simple pin fixation, which is susceptible to loosening under external force, posing a safety hazard. This invention achieves more reliable fixation by providing a groove at one end of the pin to accommodate the spring end, and using a locking plate and threaded locking screws. This ensures the fence remains stable during transport, improving the durability and safety performance of the locking mechanism.

[0019] In summary, this utility model optimizes the folding and unfolding method of the fence in terms of structure, enhances the load-bearing capacity and stability of the mobile frame, and improves the fixing reliability of the support rod by adopting an improved locking mechanism. This makes the device safer, more convenient and durable during the transportation and loading of aerated concrete blocks, meeting the construction industry's demand for efficient transportation equipment.

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0028] like Figure 1 and Figure 2 As shown, a transfer device for aerated concrete block production includes a movable frame 6. A vertical support plate 1 is fixed to the upper surface of the movable frame 6 near the left end, and a handle 8 is fixed to the left side of the support plate 1. The support plate 1 is made of Q235 carbon steel with a thickness of 6mm to ensure sufficient strength and stability when bearing the weight of the aerated concrete blocks. The handle 8 is made of rubber-coated metal structure to improve the grip comfort and durability during operation, thereby improving the overall ease of use of the device.

[0029] The mobile frame 6 has six right-rotating first support rods 3 installed on both its front and rear sides. These rods are made of 304 stainless steel, with a diameter of 25mm and a length of 800mm, ensuring sufficient load-bearing capacity and corrosion resistance. A right-rotating second support rod 5 is installed on the right end of the mobile frame 6. This second support rod 5 is made of the same material as the first support rods 3 and is 900mm long, ensuring a stable enclosure structure after deployment. This improves the limiting and fixing effect during the transfer of aerated concrete blocks, preventing tilting or falling during transport. The upper ends of the multiple first support rods 3 located on the front or rear sides... The components are connected synchronously via connecting rod 2, which is made of aluminum alloy 6061 and has a diameter of 20mm. It is hinged to the first support rod 3 with high-strength bolts to ensure that the first support rod 3 can maintain synchronous movement during rotation, thereby improving the stability and ease of operation of the device during folding and unfolding. The upper ends of the two first support rods 3 and the second support rod 5 on the far right are fixedly connected by a stop rod 4, which is made of 45# steel with a galvanized anti-corrosion treatment and is 700mm long. This effectively prevents the aerated concrete blocks from tipping over during loading, thereby improving the safety of the overall structure.

[0030] Locking mechanisms 7 are installed on the left side of the support plate 1 near the front and rear sides. Locking mechanisms 7 lock and fix the leftmost first support rod 3 when it is vertical. Locking mechanisms 7 achieve precise positioning of the first support rod 3 through the cooperation of push block 72 and pin 74, improve the stability of the device during use, and ensure sufficient fixing force when the fence is unfolded to prevent the fence from loosening due to vibration.

[0031] like Figure 1 As shown, the mobile frame 6 includes a square frame welded from square tubing, with dimensions of 40mm × 40mm × 3mm and made of Q235 carbon steel. The frame is welded using CO2 gas shielded welding to ensure overall structural strength. Multiple support bars, made of 304 stainless steel, 12mm in diameter and 500mm in length, are evenly distributed within the square frame to enhance its bending strength. A 2mm thick cold-rolled steel sheet is placed on the upper side of the square frame and welded to it to form a stable load-bearing platform, improving the load-bearing capacity of the device during the transfer of aerated concrete blocks. Evenly distributed casters, 100mm in diameter, are fixed to the lower side of the square frame. These casters are made of high-strength nylon, providing excellent wear resistance and impact resistance. The casters also feature a double ball bearing structure to reduce running resistance and improve the device's mobility.

[0032] like Figure 3 As shown, guide holes 120 are provided at both the front and rear ends of the support plate 1. The diameter of the guide holes 120 is 15mm and the depth is 30mm. They are used for the precise positioning of the pin 74 to ensure the normal operation of the locking mechanism 7. A clearance opening 110 is provided on the left side of the support plate 1 at the position corresponding to the guide hole 120. The clearance opening 110 is 20mm×10mm in size to ensure that the push block 72 can be installed smoothly and has sufficient room for movement during operation.

[0033] like Figure 4As shown, the locking mechanism 7 includes a pin 74 inserted into the guide hole 120 and a push block 72 installed in the clearance opening 110. The pin 74 is made of 40Cr alloy steel, which has been hardened to a hardness of HRC55, improving wear resistance and impact resistance. The pin 74 has a diameter of 14mm and a length of 35mm, allowing it to be precisely inserted into the guide hole 120 to ensure the stable locking of the first support rod 3. A socket with a diameter of 15mm and a depth of 20mm is provided on the leftmost first support rod 3 to cooperate with the pin 74. After the pin 74 is inserted into the socket, it can achieve precise positioning, improving the stability of the fence when it is deployed. The locking mechanism 7 is designed to ensure reliable fixation. A spring 73 is installed inside the guide hole 120 to elastically push the pin 74 outwards. The spring 73 is made of 65Mn spring steel, with an outer diameter of 10mm, a length of 25mm, and a spring force of 15N. This ensures that the pin 74 has sufficient restoring force in the locked state, preventing it from loosening due to external forces. The push block 72 is fixedly connected to the pin 74 via a fixing screw 71. The fixing screw 71 is M6×12, made of stainless steel 304, and has a thread precision of 6H, ensuring a secure connection. The push block 72 can fix the position of the pin 74, improving the ease of operation and durability of the locking mechanism 7.

[0034] like Figure 4 As shown, one end of the pin 74 has a groove for receiving the end of the spring 73. The groove is 8mm deep and 5mm wide, ensuring that the spring 73 has good stability under compression and preventing it from falling off due to external force. The side of the pin 74 has a threaded hole 741 that mates with the fixing screw 71. The threaded hole 741 is M6 in size and 10mm deep, which can effectively improve the strength of the threaded connection and ensure that the pin 74 will not loosen during long-term use.

[0035] like Figure 5 As shown, a locking plate 723 is fixed to the upper side of the push block 72. The locking plate 723 is made of Q235 carbon steel with a thickness of 4mm to ensure that it will not deform under force, thereby improving the durability of the locking mechanism 7. The middle part of the push block 72 has a countersunk hole 721 for installing the fixing screw 71. The countersunk hole 721 has a diameter of 7mm and a depth of 5mm to ensure that the nut of the fixing screw 71 can be inserted into it, achieving flat installation and avoiding interference with the operation of other components. A locking screw 722 is threaded on the locking plate 723. The locking screw 722 has a specification of M8×15, is made of 45 steel, and has undergone anodizing and blackening treatment to improve corrosion resistance and service life. In the locked state, it can provide a locking torque of 25N·m to ensure that the pin 74 will not fall off accidentally during use, thereby improving the safety and stability of the overall device.

[0036] Example 2: Foldable fence structure improves loading convenience and transportation stability.

[0037] This embodiment provides a foldable fence structure. Through a reasonable linkage mechanism design, it improves the convenience of loading aerated concrete blocks onto trucks, while providing a stable limiting and fixing effect during transportation.

[0038] In this embodiment, the first support rod 3 has a diameter of 25mm and a length of 800mm. It is made of 304 stainless steel and has excellent corrosion resistance and impact resistance. The second support rod 5 has a length of 900mm and the same diameter as the first support rod 3. The upper end of the first support rod 3 is hinged to the connecting rod 2. The connecting rod 2 is made of 6061 aluminum alloy, has a diameter of 20mm, and is hinged to the first support rod 3 by M8 high-strength bolts to ensure the synchronization of the fence when it is unfolded and folded. The first support rod 3 and the second support rod 5 on the far right are fixed by a stop rod 4. The stop rod 4 has a length of 700mm, is made of No. 45 steel, and has been galvanized for corrosion protection to improve durability and bending strength.

[0039] When loading aerated concrete blocks, tighten the locking screw 722 to cause the push block 72 to drive the pin 74 to disengage from the first support rod 3. The first support rod 3 rotates synchronously to the right under the action of the connecting rod 2, causing the second support rod 5 to fold up synchronously, so that the fence is fully retracted, improving loading efficiency. After loading is completed, rotate the first support rod 3 and the second support rod 5 to the vertical position, loosen the locking screw 722, and the pin 74 automatically resets under the action of the spring 73 and inserts into the insertion hole on the first support rod 3, realizing the rapid unfolding of the fence and forming a limiting structure to prevent the aerated concrete blocks from slipping or tipping over during transportation.

[0040] Comparative Cases:

[0041] Traditional aerated concrete block transport devices mostly use fixed fence structures. These structures cannot be folded when not in use, occupying significant storage space, and require additional disassembly or detour during loading, increasing the difficulty of manual handling. Furthermore, fixed fence structures cannot accommodate aerated concrete blocks of different sizes during transport, resulting in poor stability and a tendency for blocks to tip over or be damaged. This embodiment utilizes a foldable fence structure, allowing the fence to be quickly unfolded or folded, improving the flexibility of loading and transport, while ensuring reliable limiting and fixing capabilities when the fence is vertical, thus enhancing the safety of transporting aerated concrete blocks.

[0042] Example 3: High load-bearing capacity mobile frame, improving the stability and durability of the device.

[0043] This embodiment provides a high load-bearing capacity mobile frame structure. Through reasonable material selection and reinforcement design, the stability of the device is improved, ensuring that it maintains good load-bearing capacity during long-term use.

[0044] In this embodiment, the mobile frame 6 is welded from Q235 carbon steel square tubes with specifications of 40mm×40mm×3mm, and is welded using carbon dioxide gas shielded welding to ensure the strength and durability of the welded joints; multiple support bars are evenly distributed inside the square frame, and the support bars are made of 304 stainless steel with a diameter of 12mm and a length of 500mm, which improves the bending strength of the mobile frame and enables it to withstand the weight of a large number of aerated concrete blocks; a 2mm thick cold-rolled steel sheet is placed on the upper side of the mobile frame and fixed by welding to form a sturdy load-bearing platform.

[0045] To improve mobility, this embodiment has four casters installed at the bottom of the mobile frame. Each caster is 100mm in diameter, made of high-strength nylon, and equipped with a double ball bearing structure to ensure that the wheel set can rotate flexibly under heavy load. At the same time, the casters are equipped with a braking device, which can be locked when loading into a vehicle or fixing the position to prevent the mobile frame from sliding due to inertia and improve operational safety.

[0046] Comparative Cases:

[0047] Most existing mobile frames use a single-layer thin-plate structure, which has limited load-bearing capacity and is prone to deformation under long-term stress, affecting the stability of the device. Furthermore, some mobile frames lack adjustable brake casters at the bottom, making them susceptible to displacement during transport and increasing safety hazards. This embodiment, through a square tube reinforcement structure, a support bar enhancement design, and the configuration of high-strength casters, ensures that the mobile frame remains stable under heavy loads, improving the overall service life and safety of the device.

[0048] Example 4: Optimize the locking mechanism to improve the reliability of fence fixation

[0049] This embodiment provides an optimized locking mechanism. Through a reasonable pin reset design, it improves the fixing stability of the fence, prevents the fence from loosening during transportation, and improves the convenience and safety of operation.

[0050] In this embodiment, the locking mechanism 7 includes a pin 74, a push block 72, a spring 73, and a locking screw 722. The pin 74 is made of 40Cr alloy steel, with a diameter of 14mm and a length of 35mm. It has been hardened to a hardness of HRC55, which improves its wear resistance and impact resistance. One end of the pin 74 has a groove with a depth of 8mm and a width of 5mm to accommodate the spring 73. The spring 73 is made of 65Mn spring steel, with an outer diameter of 10mm, a length of 25mm, and a spring force of 15N, ensuring that the pin 74 can quickly reset after unlocking, preventing locking failure due to external force. The upper side of the push block 72 is fixed with a locking plate 723, which is made of Q235 carbon steel with a thickness of 4mm. It is threadedly connected by an M8×15 locking screw 722, providing a locking torque of 25N·m to improve the stability of the locking.

[0051] During operation, tightening the locking screw 722 causes the push block 72 to disengage the pin 74 from the first support rod 3, thus enabling the fence to fold. After the fence is reset, loosening the locking screw 722 causes the pin 74 to reset under the action of the spring 73 and insert into the socket, thus achieving automatic locking and ensuring that the fence will not come loose due to vibration during use, thereby improving the safety of the overall device.

[0052] Comparative Cases:

[0053] In existing technologies, some transfer devices use a simple pin insertion method for locking mechanisms. Over long-term use, these pins are prone to falling off due to external forces, causing the fence to loosen and affecting the stability of the aerated concrete blocks. Furthermore, some locking mechanisms lack an automatic reset function when locked, leading to cumbersome operation and reduced ease of use. This embodiment improves the reliability of the locking mechanism through a combination of a spring reset structure and locking screws, enabling the fence to automatically lock after deployment, thus enhancing operational safety and durability.

[0054] The working principle of this utility model is as follows: When the aerated concrete blocks are being transferred and loaded onto the vehicle, the push block 72 is engaged to disengage the pin 74 from the first support rod 3. At the same time, the locking screw 722 is tightened and pressed against the support plate 1 to lock and fix the position of the push block 72. Then, the first support rod 3 is rotated to the right. At this time, under the drive of the connecting rod 2, multiple first support rods 3 rotate to the right at the same time. The first support rod 3, in turn, drives the second support rod 5 to rotate to the right through the stop rod 4, thereby completing the synchronous rotation and folding of the first support rod 3 and the second support rod 5, thus completing a convenient and quick folding operation. At this time, the aerated concrete blocks can be loaded onto the vehicle.

[0055] After the aerated concrete blocks are loaded onto the truck, the first support rod 3 and the second support rod 5 are rotated and erected. Then the locking screw 722 is loosened. At this time, the spring 73 pushes the pin 74 into the hole on the first support rod 3 to lock it, thus completing the convenient and quick unfolding operation. The erected first support rod 3 and the second support rod 5, as well as the unfolded connecting rod 2 and the stop bar 4, form a fence to block and limit the aerated concrete blocks during transportation.

[0056] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
